JOHX \VARREN JOHNSON, OF PFNDLETON, MISSOURI.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 339,659, dated April 13, 1886.

. Application filed January 19, 1586. Serial No. 159.072.

To all? whom, it may concern:

Be itknown that I, J our: WARREN J causes, a citizen of the United S ates, residing at Pendleton, in the county of \Varren and State of Missouri, have invented certain new and useful Improvements in Car-Couplings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to car couplings of that class in which the cars are automatically coupled when run together; and it has for its object to combine therewith simple and efficient devices tor mechanically uncoupling the same without the necessity of going between the cars.

To these ends, and such others as may per tain to the invention, it consists in the novel features of construction and combinations of parts more fully hereinafter set forth and claimed.

The invention is principally designed as an improvement on the device patented to me October 20, 1885, being Xo. 328,785.

In the annexed drawings, Figure 1. is an end View of a car equipped with my improved coupler. Fig. 2 is a bottom plan view of the forward end of" a car. Fig. 3 is a longitudinal section of the detached coupler on the line of Fig. 1, parts being broken away. Fig. ris a perspective view of the yoke'for operating thchooks. Fig. isa perspective view of the crank-shaft and hand-lever for actuating the yoke. Figs. 6 and 7 are detailed perspective views of connectinglinks.

The draw-bar A is of usual construction, and its shank A extends through an opening in the crossbar B, by which its rear end is supported. The front portion of the drawbar works between sills G and is sustained in position by a bar, 0, extending from one sill to the other. To limit the backward movement of the draw bar a rod, (1, is provided, and, passing through a slot therein, is held in place in the sills. A coil-spring, a, surrounds the shank of the draw-bar and has its points of resistance between the bar B and the shoulder a This spring keeps the draw-bar projected forward and serves as a cushion to lessen the jar when the cars are run together. The forward movement is limited by apin, 1), passing transversely through the shank, and adapted to impinge against the rear side of the bar B. Hooks e are pivoted within the draw-bar and are directed in their horizontal movements byguidepinsf, extending through slotsin the hooks. Springs f, interposed between the hooks and draw-bar, keep the forward ends of the hooks in close proximity. Arms 9, ex tending from the hooks slightly in advance of their pivotal points, pass through slots h h in the sides of the drawbar and sills, respectively. A yoke, G, having its ends G bent downward, and connecting with the outer ends of the arms g by means of links E, is journaled in bearings I on the upper forward edge of the drawbar. A rear extension, g, formed, preferably, by bending the yoke at its middle into a loop, is connected with a crank-shaft, J, mounted in bearings near the top of the car, by a link, j. A handlever, K, keyed to the shaft, serves as a means to rock the crank-shaft in its bearings, which motion is transmitted to the yoke and by the links E to the hooks e, to force them apart against the tension of the springs f when uncoupling the cars, as will be readily comprehended. A spring-lander, L, is located between the hooks to relieve the jar incident to the projecting of the link within the draw-bar when the cars are run together.

The link M (shown in Fig.6) is slightly curved to couple cars of different heights, and each end is arrow -shaped. This link is of wellknown shape and construction, and is simply shown to illustrate its applicability to my coupler. The link N (shown in Fig. 7) is straight and one end only is arrow-shaped. The other end is provided with aloop, a, pivotally connected therewith. By means of this link a car having the ordinary coupling may be coupled with a car having my improved coupler.

I am aware that links have been provided with an arrow-shaped head at one end and a loop at its opposite end, such loop forming an integral part thereof.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

2. In a car-coupler, the combination of a link having an arrow-shaped head and aloop I5 pivoted to its opposite end, substantially as shown, and for the purposes specified.

In testimony whereof I afiix my signature in presence of two witnesses.-

J OHb WARREN JOHNSON.
